Rhyming couplet one gets to study quickly (5-4)
I believe the answer is:
speed-read
'quickly' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'rhyming couplet one gets to study' is the wordplay.
'rhyming couplet' becomes 'speed' (I can't explain this - if you can you should believe this answer much more).
'one gets' says to put letters next to each other.
'to study' becomes 'read' (synonyms).
'speed'+'read'='SPEED-READ'
Can you help me to learn more?
(Another definition for speed-read that I've seen is " Quickly peruse".)
